Method and apparatus to enable use of motion to associate devices
First Claim
Patent Images
1. A method of associating two devices to exchange data, comprising with one device:
- receiving a signal to enter into pairing mode;
generating a key based on acceleration data, the acceleration data used to calculate a differential motion pattern performed by the device, the differential motion pattern enabling holding of the device at any angle;
establishing a secure connection with an other device, the secure connection established based on the key generated in part based on the motion pattern, the secure connection established when the device and the other device devices generate the same key based on the same motion pattern; and
exchanging data with the other device.

Abstract
A method and apparatus to provide easier pairing based on motion data is described. The method of associating two devices comprises receiving a signal to enter into pairing mode, and detecting a motion indicating a pairing. The method further comprises establishing a secure connection with another device for pairing, the secure connection established based on the motion, and exchanging data.

8. A method of associating two devices to enable an exchange of data, comprising:
-
instructing a user to hold the two devices together and perform a motion with the two devices together; calculating a differential motion data based on the motion, the differential motion data enabling comparison of motions between two devices held at different angles; and associating the devices based on the differential motion data, to enable the devices to exchange data through a secure connection, the connection secured based on identical keys generated by each of the two devices based on the differential motion data, generated when the two devices were moved together. - View Dependent Claims (9, 10, 11)

12. A mobile device comprising:
-
a motion sensor to detect movement; a pairing logic to enable data exchange with another device, the pairing logic comprising; a motion identifier to use data from the motion sensor to generate differential motion pattern, the differential motion pattern used for pairing with another device; a key generation logic to generate a key based on the differential motion pattern performed by the mobile device; a secure connection logic to establish a secure connection with the other device, the secure connection established when the key matches a key generated in the other device, indicating that the devices performed an identical differential motion pattern; and data exchange logic to exchange data with the other device over the secure connection. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
